Silence is the matrix from which word is born, the home to which word returns through understanding. Word (in contrast to chatter) does not break the silence.
In a genuine word, silence comes to word. In genuine understanding, word comes home into silence. For those who know only the world of words, silence is mere emptiness. But our silent heart knows the paradox: the emptiness of silence is inexhaustibly rich; all the words in the world are merely a trickle of its fullness.
Time is not a line but a dimension, like the dimensions of space. If you can bend space you bend time also, and if you knew enough and could move faster than light, you could travel backward in time and exist in two places at once.
